SFF gaming is tricky since airflow is a very important consideration and due to the cramped interior of an SFF machine and the fact that most decent video cards run moderately hot, you may not be able to cool the machine adequately enough and something may overheat.

What games would you want to play? And how much can you spend? Can you buy online? Do you have an OS or will you be buying one? Will you want to reuse your current HDD (recommended BTW) or buy a new one?

A way to help with cooling that does not require buying anything would be to just keep the side cover of and if possible get a fan or something to blow on the pc. Or you could possibly get a bigger case and put all the inside of the current pc into it to allow more air flow.
